Laparoscopic Transversus Abdominis Plane Block Versus Erector Spinae Plane Block in Bariatric Surgery

Laparoscopic Transversus Abdominis Plane Block Versus Erector Spinae Plane Block in Obese Patients Undergoing Bariatric Surgery: a Randomized Controlled Trial

The aim of this work is to compare the analgesic efficacy of laparoscopic transversus abdominis plane block, performed by the surgeon to ultrasound-guided erector spinae plane block, performed by the anesthetist, in patients with obesity undergoing bariatric surgery.

This is a randomized controlled trial which will include patients with obesity undergoing bariatric surgery. The patients will be randomly allocated into two groups: transversus abdominis plane block group and erector spinae plane block group. The block will be performed after induction of general anesthesia. Preoperative evaluation and preparation will include history-taking, laboratory investigation, fasting recommendations, and optimization of the medical status. The two groups will receive standard induction and maintenance of anesthesia. After the end of the operation, patients will receive standard care according to the local protocols and the enhanced recovery recommendations. Patients will be monitored according to the pain-related outcomes as well as hemodynamic parameters.

Inclusion Criteria:

• Patients with obesity undergoing laparoscopic bariatric surgery under general anesthesia.

Exclusion Criteria:

• Allergy to local anaesthetic.
• Bleeding disorders.
• Obstructive sleep apnea.
• inability to understand the numerical rating scale for pain assessment.
